Description1The mechanism of the pyroelectric nanogenerator based on a composite structure of pyroelectric nanowries..jpg
English: (a-c) Schematic diagrams of the pyroelectric nanogenerator with negative electric dipoles under room temperature (a), heated (b) and cooled (c) conditions. The angles marked in the diagrams represent the degrees to which the dipole would oscillate as driven by statistical thermal fluctuations.
